Relative Addresses used with Scoped Multicast Addresses
Reference[RFC5771]Note(*) It is only appropriate to use these values in explicitly- configured experiments; they MUST NOT be shipped as defaults in implementations. See [RFC3692] for details. These addresses are listed in the Domain Name Service under MCAST.NET and 224.IN-ADDR.ARPA. Note that when used on an Ethernet or IEEE 802 network, the 23 low-order bits of the IP Multicast address are placed in the low-order 23 bits of the Ethernet or IEEE 802 net multicast address 1.0.94.0.0.0.

How many bits are there in IP address for IPv4?
The IP protocol identifies each computer connected to the network by its corresponding address. This address is a 32 bits number in Ipv4, that has to be unique for each server or computer, which we will call “host”. The IP addresses are usually represented as four decimal ciphers, of 8 bits each, separated by dots.
